I was hoping they would come up with a mathematical way to distinguish an impossible from a 360 shuv :)

I don’t know about mathematical, but I’ve always thought of it as a vertical vs horizontal motion with the front foot used as as kind of rotation axis for an impossible…

“I know it when I see it” (maybe)

Yeah for sure, the way the foot wraps with the board is the visual cue. It has led me and friends to some fun debates in a game of skate i.e. "that wasn't an impossible", so I was hoping to be able to point to some ridiculous mathematical definition the next time it comes up.

I wonder if they have somehow mathematically proven that they are the same trick?

In which case I reject mathematics.

I was curious about this as well and gave modeling the Impossible a try... the foot drag seemed to be best mimicked by a half-kickflip, followed by a 360 shuvit, then a half-heelflip.
